While I was working on a longer text, I gathered – more or less as a by-product – information from studies and reports on the (first copy) costs of a scientific article. As a result, it can only be noted that the information available on these costs (and related costs as margins) are very different and really difficult to compare. The latter confirms my impression that there is a huge lack of transparency in the scientific publications market. The following table may give some insight in the information I found. It is also available via GitHub (https://github.com/scinoptica/article_costs.git), so please feel free to improve/ update the data or add new information.
